Abstract:

High performance computing technology developed as an accelerating speed,after the emerging of the Petaflops systems,the performance of supercomputers already increased rapidly to tens Petaflops in very short term.The general prospect by international academe and industry is that the Exascale computing system will emerge around year 2018. This paper will analyses the trend of supercomputing development based on the 39th TOP500 list, and furthermore, discuss the future Exascale computing trend and related key issues,including power consumption, scalability, reliability and programmability, etc.

Key words: exascale computing；power consumption；scalability;reliability；programmability
